STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 762,260, datedJune '7,1904;.

Application filed \opril 11, 1902.

.To all whom if; may concern.-

Be it known thatI, CHARLES A. S'roNn,a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Stop and WasteCocks; and I do hereby declare the following to be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

My invention relates to stop-valvesfor stop and waste cocks, anddesigned especially to be used in connection with Water pipes or mains.

My invention consists in forming the plug 5 of the cock with astop-armcast integral or formed integral with the plug and adapted to beextended, so as to engage with the stops on the stop-cock casing.

The object of my invention is to provide a stop-cock strong andefficientin construction,

economic in cost, and one wherein the stopcock arm m'ay be cast integraland not interfere with the grinding or fitting of the plug while it isbeing ground within its seat within 5 the casing.

Figure 1 is a view in side elevation of a cock constructed in accordancewith the present invention. Fig. 2 is a view in side elevation of thevalve-plug removed, and Fig. 3 is a simi- 3 lar view of the removableextension of the valve-plug arm.

A represents the stop-cock casing provided with the usual water andwaste Ways and the tapered seat for the plug-valve.

B represents the plug-valve, which is fitted to the seat of the casing Ain the usual manner and secured within the said seat. The plug B isfirst turned down to approximate form, so as to fit the seat in thecasing A; but 4 inasmuch as it is essential that the plug B must fit theseat in the casing fluid-tight it is necessary that the plug be groundwithin said seat,'and this operation necessitates the revolving of theplug B within the seat until the parts are snugly ground together, agrind ing material, such as fine emery andoil, being employed for thispurpose.v

Serial No. 102,416. (No model.)

In stop-cocks constructed in the ordinary manner the casing Ais providedwith stops 6 b at the upper end or near the neck of the plug B. Thestops 6 b are engaged by an arm B which extends from a cap-pieceprovided on the plugvalve and engages between the stops 1) 7), thuslimiting the rotation of the plugB within the casing A to designate whenthe cock is opened for free flow and closed with the waste-apertureopened. It is usual in constructions of this kind to make the cap Bseparate from the plug-valve, so that the said plug-valve B may beeasily turned and ground without having the arm B interfere with saidoperation, and in these cases the cap B with the arm B is removed fromthe plug B, being replaced after the parts are fitted.

The function of the cap B is to receive a wrench, and for this purposethe said cap is formed with polygonal recesses or extensions adapted tofit, respectively, the plug at its neck portion and to be engaged by ahandle or wrench, so as to turn said plug. Attempts have been made tocast the arm B integral with the plug Band to also cast the cap-piece Bintegral with said plug; but the constructions heretofore produced havebeen either expensive to manufacture or have failed on account of nothaving sufficient strength.

In order to obviate both diificulties and at the same time produce acheap and efiicient construction, I form the plug B with a head Bcomplete, so as to receive a handle or Wrench C, and also with an arm Bextending out from said head B to one side thereof, all these partsbeing cast or formed integral. In forming the arm B I prefer to cast thesame out at approximately right angles to the cap or head B and providethe same with an arm 1 and an arm 2, the latter extending slightlydownward, with its lower end clearing the upper portion of the casingAand the stops 1) 7/, thus allowing the plug B to be turned completelyWithin its seat for the purpose of grinding the same. The extension 2,however, may be dispensed with, thus bringing the arm 1 down close tothe upper surface of the casing A and in such a manner as to clear saidcasing and the stop Z) 6. After the plug B has been ground to its seat Iprovide an extension 3, which depends from the arm A in such a manner asto engage either of the stops I) b. This extension is shown in Fig. 1 inposition, in Fig. 2 removed, and in elevation in Fig. 8. In these casesit is set forth as being screwthrcaded externally at one end for thepurpose of engaging an internal screw-thread formed in the arm B Thismanner of attaching the extension, however, is not essential, as it maybe attached in any other suitable manner designed to hold the partsfirmly to gether.

By the above constructionI have provided a stop-cock having all theessential features of an eificient stop-cock with greater strength andat .a cost far beneath the usual cost of such type of cocks and onewhich may be easily assembled and reground if found necessary.

What I claim is- 1. The combination with the valve-casing provided withstops spaced apart, of the plug, an outwardly-projccting arm secured tosaid plug, said arm having an extension extending at right anglesthereto, and integral therewith,

the lower face of said extension extending above said steps so as topass the same without contacting therewith, and a'second extension ofsubstantially the same size as said firstnamed extension secured to thelatter, and adapted for engagement with said step, the upper face of thesecond extension being in abutting engagement with the lower face of thefirst-named extension, whereby any pressure on the former will be takenup by the under face of the latter.

2. In combination with the valve-casing and stops carried thereby, aplug having an arm formed integral therewith and extending above thesteps so as to pass the-same without contacting therewith, and aremovable extension carried by said arm for engagement with said stops,said extension being secured to the under side of the arm, means forsecuring said extension, said means extendinginto said arm, the upperface of the second extension being in abutting engagement with the lowerface of the first-named extension, whereby any pressure on the formerwill be taken up by the under face of the latter.

3. In combination with the valve casing formed with stops and the plugmounted therein, an arm secured to said plug, said arm at its outer endforming a downwardly-protruding extension secured thereto, saidextension being screw-threaded, and a removable extension ofapproximately the same size as said first-named extension carrying ascrewthreaded portion for engagement with said threaded portion of theextension, the upper face of said removable extension being in abuttingengagement with the under face of said first-named extension.
